- To a whom it may concern:

i end an Beit known that we, WILLIAM O. HIcKoK, 4th and JOSEPH A. SCOTT, citizens of the United St-ates, and residents of the city, county, and State of New York, and Passaic, county of Passaic, and State of New Jersey, respectively, have invented certain new and useful Improvements in Mixers, of which `the following is a speciiication.

This invention relates to improvements in mixers and especially to that class for mixing concrete, mortar and other semi-liquid or dry materials. l

One of the objects of this invention is to produce Aan improved mixer using a rotary receptacle provided with internal blades or -ledges to aid in eifectin a thorough commin ling of the materia s and to guide the iinisied product into a chute through which it asses and from which it may be removed.

ther objects will appear from the hereinafter description.

The invention embodies improvements in a mixing rece tacle,.preferably of cubical form designe to be rotated by .suitable means and so disposed that its axis of rota.. tion intercepts two of its opposite-ends or apexes.

Other contemplated improvements are hereinafter set forth.

The preferred embodiment of our-invention is set forth in the hereinafter description and illustrated in the accompanying rawin s forming part of this application. Y

eferring to the drawing in which the same reference character indicates the same part in the several views: Figure 1 is a side elevation of a mixer embodyin our improvements. Fig. 2 is an elevation of the dischar e end of the mixer. Fig. 3 is a section 0n ine 3 of Fig. 4. Fig. 4 1s a longitudinal section of the mixer showing the discharge spout vin operative position. Fig. 5 is a longitudinal detail view of the discharge spout o erating mechanism. Fig. 6 is an detail view of the discharge spout and operating mechanism. Figs. 7 and 8 are detail views of the mixing blades er ledges.

Referring to the drawings, the part marked 1 represents the mixer receptacle which is preferably cubical in form. To opposite ends of this receptacle are secured disks or wheels 2, supported on rollers 3 and operated by suitable gearing 4. The receptacle is shown with its axis of rotation intersecting two of the opppsite apexos which are suitably secured to t e disks or wheels 2, and each of which are formed with an opening, that marked 5 being the inlet or charging opening through which the materials to be mixed are introduced, and that marked 6 the discharge opening through which the mixed product 1s ejected. A suitable feed .chut 7 is in communication with the open-v Ing Thepart marked 8 represents a frame or support at the discharge end' of the receptacle to support the chute 9 which'is moved into the receptacle through the opening 6 t`o receive and conduct away the finished product.

While the mixing operation is in progress the chute is moved to the position indicated by dotted lines in Figs. land 5 and is then used as a dedector to prevent the material from being thrown out of the receptacle through the discharge opening. The use of the chute for this purpose, however, is not essential to the successful operation of the machine, and if desired, it may be swung entirely away from the discharge opening,-

mixed. The .chute 1s pivotally sup orted y the arms 10 while the material is bein depending from the rame 8. A bell crank lever 12 is pivoted on the frame,one arm of this lever being connected to one end of the chute by the link 18. t

As shown in Fig. 4 a shield 14 is preferably secured in the opening 6, and this shield has hanged portions projecting a short distance Within the receptacle. Preferabl inserted in the opening 5 is a similar s ield 14a. These shields operate as deflectors to prevent the discharge of the material from the receptacle during the operation of mix 0n the inner Wall of the receptacle and at the discharge end thereof are secured blades or ledges 15, each of these blades projecting A outwardly substantially at right angles to the wall on which it is secured. Figs. 7 and 8 are illustrations of these blades and ledges and Figs. 2, 3 and 4 show the relative positions of the same and their location during the rotation of the receptacle. These blades are substantially trough shaped and narrowest and deepest at the outlet end 16. As shown, the blade is made of a single piece of metal bent along the lines 17 and 18 to form the slantino' inner and outer walls 19 and 20. The blade is secured to the wall of the receptacle by the flanges 21 and 22. Near the outlet end of the blade the wall 19 is bent to form an angular portion 23 to deepen and narrow the trou h as well as to furnish a guide or channel or the material being mixed. The part 23 is bent baclr upon itself to form a wing 24 which bridges the space between the forward end of the blade and the wall of the receptacle to prevent the mixture from falling through the space. These blades are designed to operate as scoops and tovaid the mixing by successively lifting up and dropping the material with the mixing receptacle; hence they are essentially and primaril mixing blades, and although owm to their shape the materials being mixed all or drop from them at their outlet end, yet because of the iding 0r dellecting action of the part 23 they will not eject the material through the opening 6, but will drop it within the mixing receptacle. In order to permit these blades to discharge the mixed product, the chute 9 must be swun through the opening 6 so that the material in falling from the blades will fall on the chute and be discharged.

The operation of the machine is as follows: The receptacle is rotated at uniform speed, preferably in one direction. As each of the blades successively passes into and through the materials being mixed, it lifts a portion of the same, carries it within the pocket formed by the wall 20 until it comes to a point above the top of the contained mass and then drops the material, the latter being deflected bythe angular portion 23 and falls to the bottom of the receptacle. When the mixing has progressed sufficiently the discharge chute is swung into place andv receives the mixed material as it drops from the blades. l

- Having now described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a mixing machine, a rotary receptacle having an inlet and a discharge opening and provided with blades or ledges of trough formation, deepened and narrowed toward their outlet ends, secured to the inner wall of the receptacle.

2. In a mixing machine, a rotary receptacle having an inlet and a discharge opening, a blade or ledge of substantially rectangular formation, and having its outlet at the end nearest the discharge opening, and having an angular portion at the outlet end and disposed diagonally 'across the outlet, andsaid blade being secured to the inner wall of the receptacle.

3. In a mixing machine, a rotary receptacle having an inlet and a discharge open-- ing, a blade carried by the receptacle, said blade being of substantially rectangular form, and having its outlet end nearest the discharge opening, and having inner and outer walls, and anangular portion at the outlet end of its inner wall disposed diagonally across said outlet, and a flange extending rearwardly from said angular portion.

4. In a mixing machine, a rotary receptacle of cubical formation having its axis of rotation intersecting two of its opposite apexes, said receptacles having an inlet opening and an outlet opening, disks or wheels supporting said receptacle, rollers supporting said wheels, means for rotating the receptacle continuously in one direction during the mixing and discharge of the material, blades or ledges offtrough formation deepened and narrowed'toward their outlet ends secured to the inner wall of the receptacle, a discharge chute, and means for movingsaid discharge chute through the outlet opening and into operative position in relation to the blades.

5. In a mixing machine, a rotary receptacle having an inlet and a discharge opening, means for rotating the receptacle continuously in one direction during the mixing and discharge of the material, a blade or ledge of scoop or trough formation having a guide or delector said blade secured to' the inside of the receptacle, a disbharge chute, and means for moving said-'chute throughand away from the opening and into and out of operative position relative to said blade or ledge.

6. In a mixing machine, `a rotary receptacle having an inlet and a discharge opening, means for rotating the receptacle continuously in one direction during the mixing and discharge'of the material, a blade or ledge of substantially rectangular formation and having its outlet at the end nearest the discharge opening and having an angular portion at the outlet end and disposed diagonally across the outlet, said blade being secured to the inner wall of the receptacle, a discharge chute, and means for moving said chute through the discharge opening of the receptacle and into and out of operative position relative to said blade or ledge.

7. In a mixing machine, a rotary receptacle having an inlet and a discharge opening, a blade carried thereby, said blade being of substantially rectangular form and having its outlet end nearest the discharge opening and having inner and outer walls and an angular portion at the outlet end of its inner wall disposed diagonally across said outlet, and a flange extending rearwardly from said angular portion, a dlgscharge chute, and means 'for lmoving said chute through said discharge opening and 'Into and out of operative position relative to the blade.

In Witness whereof we have hereunto set our hands :It the city, county and State of New York this 10th day of February, 1909.
